WebThe test, called a thyroid function test, looks at levels of thyroid-stimulating hormone (TSH) and thyroxine (T4) in the blood. Doctors may refer to this as "free" T4 (FT4). A high level of TSH and a low level of T4 in the blood could mean you have an underactive thyroid. WebThyroid function tests (TFTs) The term ‘ thyroid function tests ‘ refers to the following investigations: TSH (0.4 – 4 mU/L) Free T4 (9 – 25 pmol/L) Free T3 (3.5 – 7.8 nmol/L) There are separate reference ranges for children and pregnant women. Reference ranges for TFTs often vary between labs, so always refer to your local guidelines.

WebTSH (rec-hTSH; ThyrogenTM, Genzyme). Preclinical development of superactive TSH analogs can be divided into three phases: the TSH structure-function phase, the discovery phase and the optimization phase.

TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association.

Antibodies blocking the action of TSH probably represent an important mechanism in the pathogenesis of primary hypothyroidism in some patients. fisher price side sleeper
